Insights

Seven-transmembrane (7TM) receptors form dimers, influencing their function. This review explores the biochemical evidence and functional impact of 7TM homodimerization in cell signaling.

Area of Science:

  • Biochemistry
  • Cellular Biology
  • Pharmacology

Background:

  • Seven-transmembrane (7TM) receptors are crucial signaling platforms.
  • Emerging evidence suggests 7TM receptors form homo- and hetero-oligomers.
  • Oligomerization is implicated in receptor function, but its necessity for signaling is unclear.

Purpose of the Study:

  • To review the biochemical basis of 7TM homodimerization.
  • To discuss the characteristics and organization of 7TM homodimers.
  • To explore the functional consequences of 7TM homodimerization.

Main Methods:

  • Literature review of biochemical studies on 7TM homodimerization.
  • Analysis of dimer organization and functional impacts.
  • Inclusion of select heterodimerization examples for context.

Main Results:

  • Biochemical evidence supports 7TM homodimerization.
  • Dimerization influences receptor affinity, efficacy, trafficking, and signal transduction specificity.
  • The review focuses on homodimer characteristics and functional outcomes.

Conclusions:

  • 7TM homodimerization is biochemically supported and functionally significant.
  • Understanding homodimerization is key to deciphering 7TM receptor signaling mechanisms.
  • Further research is needed to confirm if dimerization is a prerequisite for 7TM signaling.

Enzyme-linked Receptors01:00

Enzyme-linked Receptors

Enzyme-linked receptors are proteins that act as both receptor and enzyme, activating multiple intracellular signals. This is a large group of receptors that include the receptor tyrosine kinase (RTK) family. Many growth factors and hormones bind to and activate the RTKs.
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...
Multi-pass Transmembrane Proteins and β-barrels01:09

Multi-pass Transmembrane Proteins and β-barrels

In multi-pass transmembrane proteins, the polypeptide chain crosses the membrane more than once. The transmembrane polypeptide chain either forms an α-helix or β-strand structure. α-Helix containing multi-pass transmembrane proteins are ubiquitous, whereas β-strand containing ones are mainly found in gram-negative bacteria, mitochondria, and chloroplasts.

Multi-pass transmembrane proteins such as G-protein-linked receptors (GPCRs) and...
Assembly of Signaling Complexes01:30

Assembly of Signaling Complexes

Multiprotein signaling complexes are formed in a dynamic process involving protein-protein interactions at the cytoplasmic domain of transmembrane receptors or enzymatic and non-enzymatic proteins associated with the receptor. These complexes ensure the activation and propagation of intracellular signals that regulate cell functions.
Interaction domains in cell signaling
Interaction domains recognize exposed features of their binding partners containing post-translationally modified sequences,...
Receptor Tyrosine Kinases01:26

Receptor Tyrosine Kinases

Receptor tyrosine kinases or RTKs are membrane-bound receptors that phosphorylate specific tyrosine on protein substrates. RTKs regulate cellular growth, differentiation, survival, and migration. They contain an extracellular ligand binding domain, a transmembrane domain, and a cytosolic tail with intrinsic kinase activity. Several extracellular signaling molecules activate RTKs in one or more ways and relay the signal downstream. Ligands such as platelet-derived growth factor (PDGF) or...

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:
The Two-State Receptor Model01:29

The Two-State Receptor Model

The two-state receptor model explains a drug's interaction with receptors, such as G protein-coupled receptors and ligand-gated ion channels, to induce or inhibit a biological response. When no natural ligands are present, a receptor exists in an equilibrium of inactive (Ri) and active (Ra) conformations. The inactive form does not produce a response, while the active form generates a basal effect known as constitutive activity.
The binding affinity of a drug determines its interaction with one...
